JAMES WALTON, OF PIKENIOIA, NEW YORK.

GASOMETER.

SPECIFICATION forming part of Letters Patent No. 643,577, dated February 13, 1900.

Application filed August 12, 1899.

1'0 rtZZ whom it may concern:

Be it known that 1, JAMES WALTON, of Phoenicia, in the county of Ulster and State of New York, have invented a new and Improved Gasometer, of which the following is a full, clear, and exact description.

My invention relates to a gasometer in which provision is made for preventing an explosion of the gasometer in the case of an excess of pressure. To accomplish this end I construct the gasometer as willbe fullydescribed hereinafter and specifically pointed out in the claims.

Reference is to be had to the accompanying drawing, which is a vertical section of my improved gasometer.

In the gasometer-body 1 is arranged to slide vertically a bell 2, which has a conical top and a receptacle 3 surrounding said top and adapted to contain sand or water ballast. The fixed portion 1 is adapted to contain water, into which dips the bell 2 in the usual manner.

4 is the gas-supply pipe connected with any suitable generator and leading into a purifying-chamber 5, located at the bottom of the gasometer and separate from the main body thereof. In said supply-pipe 4 is arranged a valve 6 and the drain-pipe 7.

The upper section of the fixed part 1 of the gasometer is enlarged, as indicated at 8, to receive water that might be forced upward by gas-pressure, it being understood that owing to the enlarged cross-section of the said part 8 the level of the water will vary but slightly. From the cooling and purifying chamber 5 a pipe 9 leads upward in the gasometer and terminates within the bell at a point above the water-level. At the upper end of the said pipe is located a filter-sieve 10, preferably consisting of a series of superposed layers and of spherical shape. Another pipe 9*, likewise provided with a filter-sieve 10 at its upper end, leads downward from a point above the waterlevel in the bell through the gasometer and connects with the distributing-pipe 11, which leads to the burners.

A safety-pipe 12 extends upward in the gasometer and through an opening in the conical cover of the bell. At its lower end said pipe is open to the atmosphere and at its upper end it is closed by a cap 13, and below this cap is provided a port 14, so arranged as to be within the hell 2 when the same is in its high- Serial No. 727,051. (No model.)

est positionthat is, in contact with the cap 13. Within the bell, which is guided by sliding upon the pipe 12, is located a sleeve 15, which extends nearly to the bottom of the bell at a slight distance from the safety-pipe 12, which it surrounds. 16 is a drain-cock for the main body of water in the gasometer.

In operation the gas flowing through the supply-pipe 4 first passes into the cooling and purifying chamber 5 and then rises through the pipe 9 and filter-sieve 10 into the hell 2. From there the gas passes downward through the pipe 9 to the distributing-pipe 11. 4 Should at any time the pressure within the gasometer become excessive, the bell will rise until it strikes against the cap '13, and in such position the aperture 14: will be within the annular space between the sleeve 15 and the pipe 12, so that the excess of gas will rush out from the gasometer through the said port 14 and the pipe 12. As soon as the excess is relieved the gasometer-bell will fall, so as to bring the port 14 to the outside of the gas- I ometer, thus avoiding any waste of the gas. Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A gasometer comprising a fixed part and a movable bell, a pipeleading upward through the top of the bell and having a port below its upper closed end, and a sleeve supported and carried by the gasometer-bell and surroundingthe said pipe, substantially as described.

2. A gasometer comprising a fixed part and a movable bell, and a stationary pipe leading upward through the top of the bell and having a port below its upper closed end, said port being arranged to com municate with the interior of the bell when the latter rises abnormally high, substantially as described.

3. A gasometer comprising afixcd part and a movable bell, and a stationary pipe extending through the top of the bell and provided with a port below its closed upper end, and with a cap or stop above said port to arrest the upward movement of the bell when the said port is in the interior of the bell, substantially as described.

JAMES WALTON.
